Application filed July 11, '1910. Serial No. 571,287.

carried upon crank pins 'in cranks 6,"which Be it known that we, VICTORE. EDWARDS are attached to rotating shafts 7, 7, so that I and JEROME R.GEQRGE, citizens of the United States, residing at \Vorcester, in thecount-y of lVorcester and Commonwealth of Massachusetts, have invented anew and useful Improvement in- Conveyers for Metal Rods, of

which the following is a specification, ac-

- a rolling mill by a longitudinal movement heated metal rods of therod'and to convey the same by a sidewise movement, having means forsupporting the rods during said sidewise movement and during the periodof cooling. In the,

present instance we have shown our inven 'tion as e'mbodied in aconveyer having ase- .rie's'of stationary supporting bars provided withnotches in alinementf in which the p are supported 1 and straightenedduring the proeessot cooling,

jand a series of movable notched bars by metal rods, as they are movedforwardby a' I which the heated metalrods are moved forward by asidewise step-byestep movement from one line of notches to the nextsuceeed ing line.

Our present-invention relates to the means for controlling the movementot the'heated .rods as they are delivered to the mechanism fortransferring them by a sidewise step-bystep movement, and our inventionconsists in the construction and arrangement of parts by which this isaccomplished as hereinafter described and I pointed out in the annexedclaims, 1 p

In the accompanying drawings Figure 1 represents a side View of aportion of a con-v veyer embodying our invention. F ig. 2 is a planview. of that part shown in Fig, 1.

Referring to tl1e ,accon'1pany ng drawings, 1 denotes a series ofparallelstationary supporting bars provided with angular'i iotches 2,each set of notches in the bars 1 be ng arranged in alinc'ment to enablethe heated notchesQ. v I I 3 denotes a .b'eries oft parallel movablebars 'hrn-inzx.notches 4-. The movable bal'sl-S are the bottom of eachof the notches 4 wil l travelthrough a circular path correspond ing tothe path of the crank pins 5. 'At the receiving end of the notched barsl'we mount a stationary inclined plate 8,-haVing. at its lower edge anupturned flange "9 form- In the supporting framework ofthe conveyer arejournaled conical conveyer rolls 12 in alinement with each other andpositively driven through a geared connection 13 from a commondrivingslraft 14. The conveyer rolls'12 are. arranged to receivea rod orbarf from a rolling mill by a longitudinal movement across theperipheries of the conveyer rolls. The upper-surfaces of the conveyerrolls lil'project slightly through openings 15 in the plate 8, to enablethe rod or bar to be; longitudinally moved by contact with the rolls. Asthe rolls are conical, their peripheral speed, andc'onsequently thelongitudinal speed of the .rods resting thereon, I

will vary with difi'erent planes of rotation.

Mounted above therolls 12 in brackets 16 is a rocking shaft 17 provided,at any conxcnient position. with a, radial halid'lever 18 and alsocarrying the radial arms 19,110 the lower ends of which a plate 20 isprefer,- ably attached. capable of a swinging movementorer theperipheries of the rolls 12.2.

By rocking the shaft 17 the position ofa rod 21 on the rolls can bevaried, thereby pro-- during 'a corresponding variation in the speed ofits longitudinal movement. Ifthe rod is supported upon the conical rollsnear their larger ends,the'longitiulinalispeed of the rod will begreater than whensupported near the smaller ends ot therolls, and'anyivariation in the longitudinal speed may be vproghu-od livchanging thepositionof the rod upon the rolls. 7 By depressing the lever,hainlloltl, the shaft-,l'lnmy beiroclcedsuthciently-to bringtlie arms10 and plate 20,

entirely clear of t-h'rolls 1; allowing the rod 21, to roll off thesmalleronds of the rolls.

upon the plate 8 and into the trough 10 in \rhiclit'ho rod issupportedsubstantially for movement of the 65 the ,rolls and delivered atoucejinto the ported entire len h upon the plate,

I and,.at, each succeeding movement of the movablebars 3, the rod. willbe carried 'step-' p its entire length, enabling the 'heatedg rod to,

become straightened by its contact with the walls of the trough 10.v I 1As' the rod is delivered from the mill itis received upon that-portionof the rolls where the peripheral speed of the rolls approximates thelongitudinal speedof the rod 'as imparted by the last pair of rolls inthe mill. When -the rod;is free from the 1 mill, and before it isdelive'red to the trough 10, the speed of the rod is retarded by, move-Y ment toward the smaller ends of the conical I rolls so that thenioment-urn will be substantially checked before it coine'sjin contactwith the sides of the'trouglr-10. This retardation is accomplishedby'holding 'the rod for a period upon the smaller ends of 1 the. rollsinstead of allowing it to be moved rapidlyby gravity over the smallerends of i trough "10. v a

1 1 In the normal position'oflthe arms 19 and plate 20,, latter isheldat substantially right angles with the rod supporti surfacethe'arms19 may be swung toward .t e trough, in which the rod is proected forward and against the sides of which it-is pressed by hgravity,' w hile in a state of considerable heat, thereby causing itto.be straightened by its. so contact with the plate -8 and late 20.Im-' mediately' behind the free on of the-arms. 19, when in their normal'plositiom-the plate 8 is slightly depressed to a ow the free ends ofthearms 1 9 and lower edge of the plate 20 to project below the plane ofthe supporting surfaces of the conveyer rolls, so that the arms 19 maybe swung toward the trough 10 some distance and still retain-the rodupon the smaller ends of the rolls sufiiciently long to retard'f-thespeed of the rod. The heated rods when-finally delivered from thesmaller. ends of the conical rolls, are supover-which they slide siewise into the ri ht angled trough 10, and-are held by grav ty againstbothsides of the trough until they are'- lifted"therefrom by the u wardmove; ment of the conveyer bars 3, thereby-again tending to straightenthe rods. 7 When the rod; is held in the-trough 10 and the movable bars3 are in operation, the first row of notches 41in the movable bars willpickup the rod from the trough 10a'nd de- 1 posit; it inthefirstrowofnotches 2"in the stationary,barsi 1."
